OpenXR Motion Reprojection 'Always On' Crash on 2.8.2.35759 Open Beta

[Munkwolf]

@BIGNEWY new post with dcs.log attached as requested

When motion reprojection is set to 'always on', DCS loads ok, but a few seconds or so after entering the hangar the view will stop updating. It's not a hard crash, DCS stops responding and must be force-closed.

Same for me.

Mine hangs part way through loading a mission. Turn off reprojection and it loads fine.

Deleting my FXO and metashaders2 folders seems to have fixed the issue !

Edit : Scratch that I still have crashes but they are more random.

@BIGNEWYI can confirm that the hotfix has not resolved the motion reprojection error

Small follow-up.. as someone mentioned in the native openxr thread, going back to opencomposite and not using the new command parameters does allow motion reprojection 'always on' to work.

Experiencing the same issue, unable to use motion reprojection with OpenXR in the latest update.  MR makes the game very smooth on my 5800X3D/3080, without it it’s a little stuttery sometimes.  When I enable MR in OpenXR Toolkit, the game crashes at the main menu.

I can go back to opencomposite, but the game doesn’t perform as well as before the hotfix.  Neither does SteamVR.

Same for me.

On a side note: was it really smooth for you with MR in Opencomposite? For me, combo boxes in settings are all jumping around with MR on and in game I also get distorions like flapping wings when I look back etc. Reverb G2, RTX3080, Win10.

Yes, mine was very smooth, no issues or artifacts except for occasionally when the scenario was very loaded up in close proximity to an enemy fighter at the merge, for example.

@BIGNEWYany update on a fix for this? Thank you 

Update: Using OpenXR toolkit (with the fix for this) has solved issue. Thanks

The OpenXR Toolkit now includes a fix for motion reprojection with DCS in native OpenXR mode:
